I have already made reference to this elsewhere, but other Sony users may be unaware. It would appear that Sony are no longer going to write/commission their own software in future, but are going to deliver Phase One's Capture One raw converter with their cameras. Capture One Express for Sony can be downloaded free of charge from Phase One. To upgrade to Capture One Pro for Sony costs a modest €23 plus VAT, a fraction of the upgrade cost to the full (non Sony) Pro version. The current version is 8.1, and I prefer it to both DxO Optics Pro, and Adobe LightRoom for raw conversion. Version 8.1 can also be fitted into a LightRoom workflow if you use LR for cataloguing your images, and can also pass images into Photoshop.
